JavaScript比較兩個時間的大小和時間差
<script type="text/javascript">
$(function () {
---------------------------------比較時間的大小-------------------------------------------------
var cha = (Date.parse("2010/1/14 9:00:00") - Date.parse("2010/1/12 8:00:00")) / 86400000 * 24;
if (cha > 0) {
alert(cha);
}
---------------------------------比較時間的大小-------------------------------------------------
alert(daysBetween("2010-1-13 8:00:00", "2010-1-12 6:00:00"));
---------------------------------得到當前時間-------------------------------------------------
var date = new Date();
now = date.getFullYear() + "/";
now = now + (date.getMonth() + 1) + "/"; //取月的時候取的是當前月-1如果想取當前月+1就可以了
now = now + date.getDate() + " ";
now = now + date.getHours() + ":";
now = now + date.getMinutes() + ":";
now = now + date.getSeconds() + "";
alert(now);
---------------------------------得到當前時間-------------------------------------------------
-----------得到一個區域的時間，然后計算出時間差，并顯示到指定的位置---------------------------
$(".cuttime").each(function () {
var txt = $(this).text();
var endtime = txt.substring(0, txt.indexOf('至'));
var starttime = txt.substring(txt.lastIndexOf('至') + 1);
var cuttime = (Date.parse(starttime) - Date.parse(endtime)) / 86400000 * 24;
alert(cuttime);
$(this).next("td").text(cuttime);
});
-----------得到一個區域的時間，然后計算出時間差，并顯示到指定的位置---------------------------
alert(changetime("2010-1-12 8:00:00"))

//比如2011$1$1，把“-”改成“$”

//計算兩個時間相差幾天時用的語句
